I don't think we can simply call blk_queue_flush - we must ensure to never set more bits than the device allows. We'll just need two sets of flags in the request queue, with the sysfs file checking that it never allows more flags than blk_queue_flush. I'll prepare a patch for this on top of the current series. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
